Abstract

Abstract: In the regional power grid with high wind power penetration rate in China, the wind power has anti-peaking characteristics, which harms the safe operation of the power system. The source side regulation are gradually lacking, and developing the peak-shaving capability of distributed electric heating load is an effective way to solve this problem. In this paper, an electric heating load model based on building parameters and a peak-shaving capability evaluation model are established. Then the peak-shaving experiment is carried out to verify the feasibility and fit the model parameters in the severe cold region. Finally, on the basis of simulation, the peak-shaving capability of typical residential building in the severe cold region is given from two aspects: time-shift power and peak-shaving cost. And the factors affect the time-shift power and peak-shaving costs are analyzed.

Key words: electric heating load, peak-shaving capability, time-shift power, peak-shaving cost
